New Carseat?

My DD is very tall for her age she is 28 3/4 inches and 18lbs *she had her 6 month well visit last week* According to the limits for her infant car seat it is time for us to invest in a new one (I can't believe how fast that went!!!) Have any of you bought the next size? Did you get the covertible kind? What brand would you recommend?

diono radian 120. we were gonna get the rxt- but the head wings make it outgrown quicker due to the shoulders hitting them.

diono or britax are highly rated & have high weight limits. diono goes a bit bigger & is better for tall kids- whic i would recommend for you. it goes up to 57", 120 pounds as booster, and rear faces the longest- 45 pounds, which is important for safety.

britax marathon or advocates are outgrown quicker than dionos- mainly in height.

For convertible carseats, I love the Evenflo Triumph Advance (maybe it's called Triumph 65 now?). Used to be available at Target, might still be. It's well rated, relatively affordable (maybe $120? not sure) and SUPER EASY to adjust. That for me is the selling point right there (-:

It seems really comfy for ODD; she was able to comfortably rear-face in it (in the middle spot, backseat of sedan) until almost 2.5 years!

Thanks ladies. Callie is 18lbs and almost 29 inches. My seat goes to 28.5 inches and 22lbs so in the weight requirement she's not there yet just super long. My car is small (Mazda3) so I'd like something that isn't too bulky while rear facing. I guess I'll take your advice and go try her out in a few. I'll also see how it looks rear facing.

A Graco size4me 70 (mysize 70 at BRU) is what I want. It works well for tall babies-britax marathons are quickly outgrown by tall children. It is narrower than the myride and has a no rethread harness and reclines. It also doesn't take up a lot of space front to back.
